BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to a knitting field, and moreparticularly, to a comfortable anti-off sock and a knitting methodthereof.

Description of the Related Art

In order to adapt to foot wearing, a “line-heel” or “Y-heel” technologywas often adopted when a sock heel of a conventional sock is knitted.That is, a corresponding knitting structure is formed by apicking-inserting-needle knitting method along the “line” or “Y”.

The problem is that the knitting length of the knitting structure of the“line-heel” is limited by the manufacture equipment to a great extent,as a result of which the manufactured sock is difficult to achieve adesired shape; and due to an impact of the knitting technology, an angleof a bifurcation part of the “Y-heel” is basically limited to about 45°.If the size of the sock heel is needed to be enlarged according to afoot type, as the angle of the knitting structure is limited, the sockshape will be loosed, which cannot achieve an effective anti-off effect.In addition, due to a conventional sock toe knitting technique, theposition of the sewing loop is close to the front of the toe, easy toslip and poor in wrapping performance.

BRIEF SUMMARY OF THE INVENTION

Aiming at above problems, the present invention provides a comfortableanti-off sock and a knitting method thereof to solve the problem of pooranti-off effect of socks in the prior art.

A technical solution adopted by the present invention is as follows: asock includes a sock toe, a sock body and a sock heel; both the sock toeand the sock heel are connected with the sock body; the sock is providedwith a first knitting structure and a second knitting structure; and thefirst knitting structure includes a first picking-needle area and afirst inserting-needle area located at one side of the firstpicking-needle area near the sock toe. When the second knittingstructure is a picking-needle structure, a second picking-needle area isformed, and the second picking-needle area links the firstinserting-needle area; or when the second knitting structure is aninserting-needle structure, a second inserting-needle area is formed,and the second inserting-needle area links the first picking-needlearea.

A picking-inserting-needle knit formed by the first picking-needle areaand first inserting-needle area with the first knitting structuresconnected with each other is located at the sock. Then a loop-formingnumber is increased by combining with the second picking-needle area orsecond inserting-needle area of the second knitting structure. As thefirst knitting structure and the second knitting structure are connectedtogether, when the sock is pulled, the sock can have a more uniform andlarger range stretch, which ensures the wrapping performance andanti-off and anti-slide effects of the sock.

In one embodiment of the present invention, the first knitting structureand the second knitting structure may be located at the sock heel. Thesecond knitting structure may include the second picking-needle area,and the second picking-needle area may link the first inserting-needlearea.

In one embodiment of the present invention, the number of loops of thefirst picking-needle area may be equal to the number of loops of thefirst inserting-needle area.

In one embodiment of the present invention, the number of columns of thefirst picking-needle area may be less than the number of columns of thefirst inserting-needle area.

The sock will be stretched when the sock is put on or took off, and bothborne stress and deformation amount of the first knitting structureextending toward the sock heel from the sock body during the stretchingprocess are relatively large, while since the extending direction of thesecond knitting structure is toward the sock toe and an angle betweenthe second knitting structure and a stretch direction of the entire sockis relatively small, the borne stretch stress is relatively small. Alarger number of loops on the first knitting structure are knitted thanthose on the second knitting structure, such that the deformation andthe borne stress of the two knitting structures are more uniformedduring bearing the stress, and the sock structure is kept to be stableand not easy to be loosed.

In one embodiment of the present invention, the first knitting structuremay form a sock heel main gore line, the second knitting structure mayform a sock heel side gore line, and a length of the sock heel main goreline may be greater than a length of the sock heel side gore line.

In one embodiment of the present invention, the first knitting structureand the second knitting structure may be located at the sock toe. Thesecond knitting structure may include the second inserting-needle area,and the second inserting-needle area may link the first picking-needlearea.

As the shape of the sock toe part is relatively regular, both stretchesand stresses in different directions are relatively uniform, the secondknitting structure toward the sock sole directly adopts the secondinserting-needle area to increase a stitch number of the loop-formingpart at the sock sole. Then through the picking-inserting-needlestructure, the first knitting structure toward the sock toe strengthensthe connection between the knitting structures and optimizes the sizeand structure of a sock surface. The knitting structure with anincreased loop-forming number at the sock sole wraps more closely anduniformly, which improves the comfort of sock wearing.

In one embodiment of the present invention, the number of columns of thefirst picking-needle area may be equal to the number of loops of thesecond inserting-needle area.

In one embodiment of the present invention, the first knitting structuremay form a sock toe main gore line, the second inserting-needlestructure may form a sock toe side gore line, and a length of the socktoe main gore line may be greater than a length of the sock toe sidegore line.

In one embodiment of the present invention, an included angle of thefirst knitting structure and the second knitting structure may rangefrom 60° to 150°.

The first knitting structure includes a picking-inserting-needleknitting structure used for strengthening the connection, and the secondknitting structure includes a picking-needle knitting structure used forreducing loop-forming stitch number of the sock and an inserting-needleknitting structure used for increasing loop-forming stitch number of thesock. The connection performances of different knitting structures onthe sock body are also different. Set the stretch directions of thefirst knitting structure and the second knitting structure at about 90°,that is, when the two knitting structures are perpendicular to eachother, the action between the knitting structures can be the largest andcannot be offset by each other, and the improvement of the stretchperformance to the sock sole is most obvious. As the sock is made offlexible fabrics, the shape is not easily to be completely fixed.Therefore, in actual products, all knitting structure arrangements atabout 90° can achieve similar effects.

In an embodiment of the present invention, the knitting method uses acircular knitting or a weft knitting technology, and the knitting methodincludes: S11: knitting a first knitting structure: knitting a firstpicking-needle area, then knitting a first inserting-needle area at anend of the first picking-needle, and the first inserting-needle arealinking the first picking-needle area; and S12: knitting a secondknitting structure: when the second knitting structure is apicking-needle structure, knitting a second picking-needle area at anend of the first inserting-needle area after knitting the firstinserting-needle area in step S11; or when the second knitting structureis an inserting-needle structure, knitting a second inserting-needlearea first before knitting the first picking-needle area in step S11,and an end of the second inserting-needle area linking the firstpicking-needle area.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will be described in detail below combining withthe accompanying drawings.

As shown in FIG. 1 and FIG. 2, which are schematic diagrams of knittingstructures, 0 represents not forming a loop (no loop-forming), and 1represents forming a loop (loop-forming). The inserting-needle structureis the knitting structure that the stitch number of each loop increasesgradually with the increasing of the knitting loop-forming, and thepicking-needle structure is the knitting structure that the stitchnumber of each loop decreases gradually with the increasing of theknitting loop-forming due to picking up the needle. As the firstknitting structure 21 and the second knitting structure 22 are connectedtogether, when the sock is pulled, the sock can have a more uniform andlarger range stretch, which ensures the wrapping performance andanti-off and anti-slide effects of the sock.

Please refer to FIG. 3 to FIG. 7. The embodiment of the presentinvention provides a comfortable anti-off sock. In the figures, solidlines represent the picking-needle structures, and dot-dash linesrepresent the inserting-needle structures. The sock includes a sock toe11, a sock body 12 and a sock heel 13; both the sock toe 11 and the sockheel 13 are connected with the sock body 12; and the sock has a firstknitting structure 21 and a second knitting structure 22. Wherein thefirst knitting structure 21 includes a first picking-needle area A1 anda first inserting-needle area B1 connected to each other, and the firstinserting-needle area B1 extends out from one side of the firstpicking-needle area A1 toward the sock toe 11.

When the second knitting structure is a picking-needle structure, asecond picking-needle area A2 is formed, and the second picking-needlearea A2 links the first inserting-needle area B1; or when the secondknitting structure is an inserting-needle structure, a secondinserting-needle area B2 is formed, and the second inserting-needle areaB2 links the first picking-needle area A1.

When the first knitting structure and second knitting structure are onthe sock heel 13, the second knitting structure 22 includes the secondpicking-needle area A2, and the second picking-needle area A2 isconnected with the first inserting-needle area B1. Combining with theexpanded diagram, the first picking-needle area A1 in the first knittingstructure 21 exhibits a trapezoid eeff (sstt) with a gradually decreasedstitch number of its loop toward the sock sole 14, and the firstinserting-needle area B1 exhibits a trapezoidal f′f′e′e′ (ttrr) shapewith a gradually increased stitch number of its loop away from the socksole 14. The second picking-needle area A2 in the second knittingstructure 22 links the first inserting-needle area B1 of the firstknitting structure 21, exhibiting a trapezoidal e′e′g′g′ (rruu) shapewith a decreased stitch number of its loop toward the sock sole 14.

As a preferable Embodiment I of the present invention, the number ofcolumns of the first picking-needle area A1 is equal to the number ofcolumns of the first inserting-needle area B1, that is, the start pointe of the first picking-needle area A1 on the expanded diagram and theend point e′ of the first inserting-needle area B1 are aligned with eachother.

As a preferable Embodiment II of the present invention, the number ofcolumns of the first picking-needle area A1 is less than the number ofcolumns of the first inserting-needle area B1, that is, the start points of the first picking-needle area A1 on the expanded diagram and theend point r of the first inserting-needle area B1 are not aligned, andthe horizontal distance of st is shorter than the horizontal distance oftr.

When knitting the sock, taking e (s) as the start point, knit the firstpicking-needle area A1 of the first knitting structure 21 toward thesock sole 14 to form a sock heel main gore line of (st), and then takingthe f′ (t′) aligned with the f (t) as the start point, start to knit thefirst inserting-needle area B1 in the first knitting structure 21 untilends at the point e′ (r); and then taking e′ (r) as the start point,knit the second picking-needle area A2 in the second knitting structure22 to form a sock heel side gore line e′g (ru). Preferably, the lengthof the sock heel main gore line of (st) formed by the first knittingstructure 21 is greater than the length of the sock heel side gore linee′g (ru) formed by the second knitting structure 22.

The sock will be stretched when the sock is put on or took off, and boththe borne stress and deformation amount of the first knitting structure21 extending toward the sock heel 13 from the sock body 12 during thestretching process are relatively large, while since the extendingdirection of the second knitting structure 22 is toward the sock toe 11and is parallel to the stretch direction of the entire sock, the bornestretch stress is relatively small. The length of the sock heel maingore line formed in the first knitting structure 21 is greater than thelength of the sock heel side gore line of the second knitting structure22, such that the deformation and the borne stress of the two knittingstructures are more uniformed during bearing the stress, and the sockstructure is kept to be stable and not easy to be loosed.

Please refer to FIG. 8 and FIG. 9. When the first knitting structure andsecond knitting structure are at the sock toe 11 of the sock, the firstknitting structure 21 includes the first picking-needle area A1 and thefirst inserting-needle area B1 connected with each other, and the firstinserting-needle area B1 is at one side of the first picking-needle areaA1 toward the sock toe 11. The second knitting structure 22 includes asecond inserting-needle area B2, and the second inserting-needle area B2links the first picking-needle area A1. Combining with the expandeddiagram, the first picking-needle area A1 in the first knittingstructure 21 exhibits a trapezoid JJKK with a gradually decreased stitchnumber of its loop near the sock sole 14, and the first inserting-needlearea B1 exhibits a trapezoidal K′K′J′J′ shape with a gradually increasedstitch number of its loop away from the sock sole 14. The secondinserting-needle area B2 in the second knitting structure 22 links thefirst picking-needle area A1 of the first knitting structure 21,exhibiting a trapezoidal HHJJ shape with an increased stitch number ofits loop away from the sock sole 14.

As the shape of the sock toe 11 part is relatively regular, bothstretches and stresses in different directions are relatively uniform.The second knitting structure 22 toward the sock sole 14 directly adoptsthe inserting-needle knitting to gradually increase the stitch number ofthe loop-forming part at the sock sole. Then through the structuresincluding the first inserting-needle area B1 and the firstpicking-needle area A1, the first knitting structure 21 toward the socktoe 11 strengthens the connection between the knitting structures andoptimizes the size and structure of the surface of the sock. Theknitting structure with an increased stitch number at the sock sole 14wraps more closely and uniformly, which improves the comfort of sockwearing.

Preferably, the number of columns of the first picking-needle area A1 onthe sock toe is equal to the number of columns of the firstinserting-needle area B1, that is, the start point J of the firstpicking-needle area A1 on the expanded diagram and the end point J′ ofthe first inserting-needle area B1 are aligned with each other.

When knitting the sock, taking H as the start point, knit the secondinserting-needle area B2 in the second knitting structure 22 away fromthe sock sole 14 to form a sock toe side gore line HJ. Then taking J asthe start point, knit the first picking-needle area A1 in the firstknitting structure. Then taking the point K′ aligned with the point K asthe start point, start to knit the first inserting-needle area B1 in thefirst knitting structure 21 until ends at the point J′ to form a socktoe main fore line. Preferably, the length of the sock toe main goreline JK formed by the first knitting structure 21 is greater than thelength of the sock toe side gore line HJ formed by the second knittingstructure 22.

Preferably, an included angle between the first knitting structure andthe second knitting structure ranges from 60° to 150°. Set the includedangle between the first knitting structure and the second knittingstructure at about 90° through the technology at the setting stage, thatis, when the two knitting structures are perpendicular to each other,the action between the knitting structures can be the largest and cannotbe offset by each other, and the improvement of the stretch performanceto the sock sole is most obvious. As the sock is made of flexiblefabrics, the shape is not easily to be completely fixed. Therefore, allknitting structure arrangements approaching 90° can achieve similareffects.

As shown in FIG. 10, the dotted line represents the position of thesewing loop in the existing knitting scheme, and the solid linerepresents the position of the sewing loop after adopting the technicalsolution of the present invention. After adopting the knittingstructure, the position of the seaming loop of the sock toe moves to therear of the toes under the stretch action of the knitting structure,making the position more reasonable and improving the wrapping comfortof the sock to sole of the foot.
